V UNITED STATES PATENT ferries JAMES .:r., SMALL, or FAIRFAX, .ivr ssoun RAILWAY-orig n.

To all whomz't may concern:

Be it lrnown that I, JAMES J. S1\[ALL,L citizen of the. United States, residing. at Fairfax, inthe county of Atchison andj State of Missouri, have invented certain new and useful Improvements in Railway-Gates, of whlch the following is a specificatlon.

This invent on relates to railway gates,

and more particularly to gates of thistype which are ,designed to prevent stock from getting on the track.

The invention has for its object to provide a novel and improved gate of the kind stated which is normally closed and which is automatically opened by a train approachingthe same, and is held open while the train is passing, after which it is again closed.

The object stated is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood reference is had to the accompanying drawings, in which Figure 1 is a plan View of the invention; Figs. 2 and 3 are longitudinal sections on the lines 2-2 and 33, respectively, of Fig. 1, and Fig. 4 is a cross-section on the line 1-4 of Fig. 1.

Referring specifically to the drawings, 5 denotes the rails of a railroad track, the same being mounted on cross ties or string ers 6 in the ordinary manner. At the place along the track Where a cattle guard is necessary or desirable, is mounted a double gate, the two members of which are inclicated at 7 the same being mounted respectively, on opposite sides of the track and so dimensioned and ositioned that they swing transversely of tie track, and meet at the middle thereof when in closed position. It

will be understood, of course, that'a single gate or door, reaching across the track, may be employed with equal facility.

Each gate 7 is fastened at its inner end to an upright post 8 which is rotatable and stepped at its lower end in a cross sill 10 extending beneath the track. The top of the post is journaled in a bearing 11 carried by an upright 12 rising from the sill 10 and suitably braced. The gate may also be formed integral with the post.

The gates 7 are normally closed and they thus prevent cattle from getting on the track. In order that the gates may be automatically opened to permit the passage of Specification bf Letters Iatent.

nism is provided: On opposite sides of the h latentedDec. 19, 1916. Application filedOctober 5,1915. sei iainese sa V I trains overtheftrack, ,thefollowingmechw gate 7-, some distance therefrom, are mounted rollers 13 located beneath the rails and extending. transversely of the track. The

rollers arejournaled in suitable bearings 14.

, ()n theends of the rollers are wo-undcables extending along thetrack and connected. intermedlate their ends tothe pivot posts 8,

of the gatesby being wound around the same, ,To the rollers 13 are fixed tappet armslfilwhich arelocated between the track rails 5,,and arenormally upstanding so as to be inathe pathof-the pilot ofthe locomo-, tive. The rollers are connected by longitu dinal bars 17 positioned alongtheinnersijde.

,ofthe track rails, in proximity thereto, and

at such an elevation that they are in the path of the flanges of the car wheels. The connection between the rollers and the ends of the bars is made by means of staples 18- carried by the rollers, and eyes 19 at the ends of the bars, through which the staples looselypass. This provides a loose connection between the rollers and the bars. To each roller is also fastened, and partly wound, a cable 20 having connected to its free end a coiled spring 21 which is anchored to one'of the ties 6. The springs 21 are for the purpose of turning the rollers in a direction to restore the tappet arms to upright position, and for closing the gate.

The gatepperating mechanism works as follows: The gates 7 are normally closed, they being held in this position by the springs 21 and the connections between the rollers '13 and the gate pivot posts 8. The tappet arms 16 are also normally in upright position, in which position they rise to a suflioient height to be struck by the pilot of an. approaching locomotive. When the pilot strikes the tappet arm on that side of the gate from which the train is approaching, the roller 13 to which said tappet arm is connected turns in a direction to unwind the cables 15 thereon, the cables winding on the other distant roller, the latter'being turned by the connecting bars 17. By this operation of the cables, the pivot posts are rotated in a direction to swing the gates open. .The gates are held open until the entire train has passed the same, as the wheel flanges ride over the bars 17 and hold the same depressed, thereby preventing the rollers from turning to close the gates. When the last pair of wheels leaves the bars 17, the

Gopies of this patent may be obtained for latter are free to rise, and the springs 21 then restore the parts to their normal position, the gates being swung back to closed position.

The operation hereinbefore described is entirely automatic and controlled by the passing train. The gates are opened by a elements positioned beneath the track on opposite sides of the gate, a connection between said elements and the gates for swinging the latter, tappets on the rotary elements and projecting above the track when the gate is closed, longitudinal bars connecting the rotary elements and extending along the inner sides of the track rails in proximity thereto to be engaged by the wheel flanges, and closing means for the gate.

2. The combination of a railway gate pivoted 'to swing across the track, a vertical pivot carrying the gate, transverse rollers mounted beneath the track on opposite sides of the gate,a cable wound on said rollers and wound intermediate its ends around the gate pivot, tappets on the rollers, and projecting above the track when the gate is closed, longitudinal bars connecting the rollers and extending along the inner sides of the track rails in proximity thereto to be engaged by the wheel flanges, and closing means for the gate.

In testimony whereof I aflix my signature in presence of two witnesses.
